Abstract: An electric cam phasing system is provided. The electric cam phasing system includes an electric motor including a center shaft; a camshaft; a center fastener extending into a center of the camshaft and a gearbox including a sprocket and a drive unit. The drive unit includes an input shaft coupling connected to the center shaft. The drive unit is configured for coupling the camshaft to the sprocket in a manner such that relative phasing of the camshaft with respect to sprocket is adjustable via the electric motor driving the drive unit. The electric cam phasing system also includes a lock positioned axially between the center shaft and the camshaft, the lock being configured for selectively engaging the center fastener to lock the gearbox.

Abstract: A continuous variable valve timing apparatus for an engine includes: a housing, a rotor installed to be rotatable relative to the housing and connected to a camshaft, a locking pin configured to restrict rotation of the rotor relative to the housing when pushed by an elastic force to move linearly and pass through a relatively rotating surface between the housing and the rotor, an elastic member installed to provide the elastic force, a valve bolt coupled to the camshaft through the housing and the rotor, wherein the valve bolt includes a release passage through which a release pressure provided through the camshaft is transferred to the locking pin via the rotor, and a valve means for selectively blocking or unblocking the release passage, and an actuator installed to actuate the valve means of the valve bolt according to an actuation displacement.

Abstract: A method for controlling a high-pressure pump for the injection of fuel into a combustion engine, the high-pressure pump being connected to a camshaft of the combustion engine, wherein the high-pressure pump is controlled in a camshaft-synchronous manner by ascertaining an angular offset between the flank positions of a camshaft pulse-generating wheel and a predefinable point above the bottom dead center of a cam of the high-pressure pump on the camshaft.
